The review step failed on a dropped model connection (RemoteDisconnected) with an unlabeled error and no retry. - Wrap transport errors with the failing operation and root cause, never including the model API URL. - Retry transport errors and 429/5xx with exponential backoff and Retry-After for GitHub reads, GraphQL and the model call. - Bound the model phase to a 12 minute budget (8 minutes per attempt) so retries fit in the 17 minute job timeout. - On an ambiguous review POST failure, re-check existing reviews before posting again so a review is never duplicated.
Non-streamed model calls that run past ~4.5 minutes are cut with RemoteDisconnected, and retrying the same request hits the same limit. Request a streamed response so data keeps arriving, and assemble the content from the server-sent events. - An interrupted or incomplete stream is a retryable transport error. - The per-read socket timeout is now an idle timeout (3 minutes); the 12 minute model budget is also enforced while reading. - A plain JSON reply is still accepted if the server ignores stream.

The Neuralink code review bot is running into API timeouts. These changes add robust retry logic and change to an HTTPS streaming request response model to mitigate this issue.
